Can't speak for everyone... But low recoil is a big factor for me. Improves accuracy, follow through, spotting impact, and ability to follow up. And then ballistically, it gives me 1600+ ft-lbs to 500y, which is all I need for the animals I hunt.Just out of curiosity why are folks doing these "improved" 708 builds to gain 100fps?? Factory hornady 150g eldx hit 2800 in 20in barrels for me. I've loaded 162g and got 2750 with sub moa grouping. The logical step would be a 7saum, then your getting 250fps more and the ability to go even heavier.
From what I know about the 7-08, it's a slower twist rate, so it doesn't handle the heavier, high-bc bullets as well, and the 30* shoulder allows for longer bullets at caliber depth seating.But what are the advantages over a standard 7mm08? Is it worth the extra effort in building a custom rifle? We can load down the 7saum to match 708 recoil bit you can't load up 7saw/08/ai to match the 7saum. I'm just curious is all and not bashing anyone's choice to build the rifle they want.
1:9.5 is SAAMI for 7-08. Which is more than enough through 160gr in lead, but in copper will limit you to about 140.1:10 is standard and 160ish is max bullet size.
Most 308 based cartridge brass is available in both SRP and LRP. It's whatever the brass maker wants to make. Or both.I have questions about the 7SAW as well...
How does a .308 based cartridge utilize a Small Rifle Primer?
Why does it use a small rifle primer?
What .308 brass has a SRP?

Energy doesn't matter. Impact velocity and bullet construction do.From what I know about the 7-08, it's a slower twist rate, so it doesn't handle the heavier, high-bc bullets as well, and the 30* shoulder allows for longer bullets at caliber depth seating.
And those things add up to lessenergyvelocity delivered down range.
That's interesting. I had no idea and I load for .308Most 308 based cartridge brass is available in both SRP and LRP. It's whatever the brass maker wants to make. Or both.
Lapua, Alpha, adg, peterson off the top of my head make every 308 and 6.5cm based cartridge in SRP and LRP.
There's a small advantage to SRP brass if you want to run it overpressure, like the SAW is. Otherwise, pick the one that you can get primers of.

That's kind of what I was thinking. I'm looking to get a 6.5CM and was thinking I should get srp brass as everywhere has sr primers in stock and they are cheap.Small Rifle Primers vs. Large Rifle Primers - RifleShooter
A close look at using small rifle primers rather than large rifle primers in reloading cartridge cases where both are offered; testing shows size matters little, with a few exceptionswww.rifleshootermag.com
This article talks about the perceived benefits, I use SRP brass in my 6.5CM because I’ve got over 5K of them and they’re easier to find than LRP.
